Zambo is live: 5 leads in 60 seconds\n\nWe built Zambo to solve one specific problem: finding qualified contractors and local service businesses without the usual manual prospecting grind.\n\nZambo Stack is now available. Give it a trade type and a city. It returns five source-backed prospects with contact info in under 60 seconds. It supports 24 trades across any US city.\n\nThere is no signup. No API key required. You get three free searches per day per IP.\n\nWe ran a live test for web design firms in Austin, TX. The system returned zero results for that specific query at the moment. This is a critical distinction: the data reflects what is currently indexed and verified. We do not guess. We do not pad lists with unverified names. If the tool finds no source-backed leads, it tells you exactly that.\n\nThis transparency is the point. Most lead gen tools sell you a spreadsheet of potential contacts that might be wrong, outdated, or generic. Zambo verifies the source before it sends the byte. A receipt proves the saved data matches the source. It does not guarantee the lead is a customer, only that the data is accurate.\n\nYou can test this yourself right now. The tool is free until you hit the daily limit. If you want to see if it works for your specific niche, run a query. If it returns leads, you have your next five conversations. If it returns nothing, you save time by not chasing ghosts.\n\nCheck the current status or run a search here: https://zambo.dev/today/k/CpYZNwc-QGiM_QH8aVMtHXEgIP6YZBrXTdn0H1WFTwhidV7iuPORU_Jw0jcAN2U6RL_SdouQzmMY1x1M6BgZjnENxyfY_t4xmi9vuv3qXRQoHk43F23qz8Q3Par8\n\nWe are not asking for trust.
